The invention relates to the field of combustible objects used in weaponry and in particular to the field of combustible cartridge cases. The combustible objects according to the invention are covered with a thin layer of varnish, based on an organic binder, containing hollow microbeads, the said varnish being based on a binder chosen from the group comprising chlorinated rubbers, polyvinylidene chloride, cellulosic binders, glycero-phthalic binders, polyurethane resins and polyepoxy resins. The varnish contains between 5 and 20% by weight, preferably about 10%, of hollow microspheres, relative to the dissolved polymer, and optionally between 2 and 15% by weight of an energy-producing charge having a self-ignition point above 200°C. The combustible objects according to the invention exhibit delayed self-ignition if they are placed in contact with a hot wall, without their thermodynamic properties being adversely affected.

A heat-resistant combustible object which is covered with a thin layer of varnish, which object exhibits delayed self-ignition in the temperature range of 200°-300°C., said varnish containing hollow microspheres, said varnish comprising as the basic ingredient an organic binder which consists of a polymer, which is a chlorinated rubber, polyvinylidene chloride, a cellulosic binder, a glycerophthalic binder, a polyurethane resin or a polyepoxy resin, the thickness of the layer of said varnish being neglegible when compared with the thickness of said combustible object.
